drm/nouveau/gr/gp10b: Use gp100_grctx and gp100_gr_zbc
gp10b doesn't have all the registers that gp102_gr_zbc wants to access, which causes IBUS MMIO faults to occur. Avoid this by using the gp100 variants of grctx and gr_zbc. Signed-off-by: Thierry Reding <treding@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
